Jupiter August 10th first of the season.

[Space Cowboy]

After taking notice of the fawlty forecast (met office app) and not going out the previous morning I was determined to try today and had success!

First Jupiter of the season and first time with the QHY 585c. Washed the primary at the weekend for the first time for over 10 years so was keen to see if I'd put everything togather properly.

Seeing was very stable and I started at 4am UT. Didn't set the ADC as I was rushing and cloud was forecast as day broke.

2 quick stacks of random shots from each end of the session (about 25 mins before it was too light).

Auto Dob 250 with QHY 585c & 2x ultima plus extension and ADC (set at neutral)

4,01 UT & 4.19 UT (2 min captures).

Very nice images and colour balance Stuart. It seems both the mirror cleaning and the new camera are performing nicely. I assume you will be stacking a few images later on.

Seeing was fantastic this morning. I have loads of captures to go through later tonight.

They are superb images Stuart. They have a great colour balance lots of contrast and plenty of detail showing not over sharpened too. A brilliant first outing of the season.

Thanks Kostas. It was similar to June on Venus at least 8/10 for stability.

Yes I'll be sorting the wheat from the chaff later and using winjupos on a few stacks.

Look forward to seeing your images! Let's hope we get this seeing at opposition!

Cheers! I like to go for the natural look. Like peeling a ripe orange the fruit should emerge without too much force if seeing is good. 😉

This could be the best one taken at 4.14 ut :

Wow! ... i think those images are fantastic and a wonderful example of not over processing and over sharpening ,  ( not that i am an expert on imaging) . 

Nice .

Indeed the seeing was excellent this morning. Even Saturn was good at 330am. The high elevation is really helpings us.

I think my best captures were a bit later at ~445 as at around 4 i could not get a very sharp focus; maybe some passing unstable seeing. But as you said not a hint of atmospheric disturbance. Looking forward to your derotated images.

Cheers Simon, it's nice to have a planet at a decent elevation again after all these years 😉

Can never get enough of the big gaseous one, great images!

Think  I prefer this version using 1.5x drizzle and combining 2 stacks in winjupos.

Dare I say the details in the very first of your images is sharper, details are easier to see.

For sure the detail is more prominent but when I looked at them on my big monitor the detail looks too bloated and they are quite noisy. Quite often what looks great on my laptop looks rough on my pc 🙂

I would definitley say the image taken at 4.14ut is the one for me Stuart. It is smooth but still retains loads of sharp details.

I agree with Martyn above that the 414 is much better in terms of details. From my experience, drizzling usually has a negative effect and I cannot get back as much details. It will be interesting to see your combined derotated images without the drizzle.

The edge rind on the left can also be tidied in registax with deringing bright side option (just a very min-mild level)

For sure as Martyn says 4.14 is the pick of the litter.  I still prefer the drizzle version on my big screen though for sure the others look better scaled down. That fine whispy detail is what I'm looking for as Jupiter is a gas planet and some images lose that gaseous feel if the detail is coarser.

This is a winjupos combo of 4.05 and 4.14 without drizzle. Much smoother than the single shots but I still prefer the drizzle 😉

I'll check that registax feature thanks Kostas!

I think that's a lot better even on big screen. It has a lot more details and still being subtle.

Thanks Kostas. Just been looking at a Jupiter shot I took back in 2012 when Jup was at opposition and at over 50 degrees elev. Quite encouraged to see how close this new image is detail wise considering its over 2 months to oppostion :

Indeed, very encouraging. Excellent image from nearly 11 years ago. No wonder you have the eye for smooth processing.

Good catches Stuart. Good detail coming through
